Gardiner, OR Coastal Erosion Rate
Shoreline change 4.1 miles northwest of Gardiner, OR
The coast 4.1 miles northwest of Gardiner, OR is actually gaining ground, not losing it: USGS's transects measure 0.82 feet of accretion a year here, sediment building up rather than washing away. At that rate, the shoreline has gained roughly 8.2 feet over the last decade.
The grain of this number
Gardiner, OR is the nearest named place, 4.1 miles away, to a ~3.5-mile stretch of coast USGS has surveyed - the reading below covers that whole stretch, not a single property in it. Segment center: 43.77, -124.17. Survey years: 2002-2011, method LRR, from USGS's Pacific Northwest shoreline-change assessment. That's how current the data is here, real, but not a live feed, since a shoreline survey is a major undertaking, not an annual check-in.
What 0.82 ft/yr means over time
Holding the 0.82 ft/yr accretion rate 4.1 miles northwest of Gardiner, OR for 25 years would add roughly 21 feet of shoreline, again assuming nothing about the local sediment supply changes.
Where this fits nationally
This reading comes from 37 individual transects averaged together, 0% of which measured erosion rather than growth. Uncertainty on this specific number: 0.52 ft/yr either side. Sorted from fastest erosion to fastest growth across all 1211 measured segments nationally, this one lands at 1082. Source: USGS Open-File Report 2012-1008. Gearhart, OR sits at national rank 1188 for growth (3.67 ft/yr), one reference point among the 1211 scored segments, 159 miles from here. 1.8 miles away, Gardiner, OR is the nearest other measured stretch: slight accretion (beach growing) at 0.59 ft/yr.
Not this whole stretch, just Gardiner itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
